METHOD OF CUTTING GLASS WITH A LASER AND AN ARTICLE MADE THEREWITH |
摘要 |
<p>METHOD OF CUTTING GLASS WITH A LASER AND AN ARTICLE MADE THEREWITH A method is disclosed for cutting glass with a laser. The glass is superposed a suitable support and a laser beam is directed onto the glass. The laser beam is focused to a point disposed at or about the surface of the glass. The focused laser beam vaporizes a first thickness of glass, less than the entire thickness, and simultaneously heats the remaining thickness above the annealing temperature of the glass. A jet of gas incident upon the laser focal point removes the heated and vaporized glass proximate the focal point to create a hole through the glass. By effecting movement between the glass and the laser and gas jet at a predetermined rate, the glass is cut. Also disclosed is an article including a unitary first sheet of glass having at least one complimental opening of predetermined configuration that does not extend to the edge of the glass and is cut by a laser. One or more complimentary glass inserts coplanar with the first glass are disposed within the opening of the first glass, defining a groove therebetween. A securing means is disposed in the groove to secure the complimentary pieces of glass in fixed edge to edge relationship.</p> |
